The Voyager Megatron from the Asian Generations series is out and photos can be seen here. The master cartons contain 2 Megatrons to one each of Hotspot & Powerdive... but still no Brawn (the fourth figure in that size class).

Seems odd that the Voyagers are being released in three waves, while all the other sizes were released at once.
Since Brawn apparently isn't being released in America, maybe it was cancelled completely.
